Is Birkenstock Stock (BIRK) Halal?

The short answer

Birkenstock (BIRK) is HALAL under ZakatInvest's qualitative core-business verdict, with a methodology-dependent current screen rather than a blanket zero-risk approval. The company manufactures and sells footbed-based footwear, skincare and accessories. Its latest balance-sheet ratios pass the examined total-assets debt, liquidity and receivables tests, but product-level revenue and gross interest income are not fully disclosed.

This is a reproducible research screen, not a fatwa or investment recommendation. Scholars and screening providers can differ on cosmetics and ingredients, leather sourcing, ownership, debt definitions, interest-income treatment and which product activities belong in a prohibited-revenue numerator.

Current quantitative screen

The calculations above use Birkenstock's official filing (Form 6-K for the period ended March 31, 2026). Amounts are in EUR millions and use total assets as the denominator so the inputs can be reproduced from the filing.

• Interest-bearing debt / assets: 22.24%, using €1,148.668 million of reported loans and borrowings. Lease liabilities are presented separately and are not added to this input.
• Cash plus identified interest-bearing securities / assets: 3.90%, using €201.467 million of cash. No separate interest-bearing securities balance is identified in the interim filing.
• Receivables plus cash / assets: 9.69%, using €298.959 million of trade and other receivables plus the reported cash balance.
• Gross interest income: unavailable. The filing reports €33.805 million of net finance cost for the quarter and €1.695 million of interest received in the six-month cash-flow statement, but does not separately disclose gross interest income.

Under the reproduced FTSE Yasaar calculation, the known ratios pass but the income input remains incomplete. The MSCI total-assets and Malaysia SAC financial-ratio calculations pass their known financial checks, while the business-activity result remains incomplete. Market-cap-denominator methods are not calculated because this site does not store a licensed, reproducible historical market-cap series for the filing date.

What Birkenstock does

Birkenstock describes footbed-based sandals and closed-toe silhouettes plus other products such as skincare and accessories for everyday leisure and work. It sells through business-to-business and direct-to-consumer channels across the Americas, EMEA and APAC. The latest issuer results report €618.333 million of second-quarter revenue, but do not provide a product-category split that would let us calculate a defensible skincare, cosmetics or accessories percentage.

Footwear manufacturing and retail are generally permissible activities. The absence of a product-level split does not prove that every revenue euro is prohibited or permissible; it means the business screen should remain explicit about what the filing can and cannot establish.

Qualitative considerations

• Skincare and accessories: the filing includes these categories but does not quantify them. Formulations, alcohol carriers, animal-derived ingredients and supply-chain evidence may matter to a scholar or investor, so the article does not repeat the old unsupported claim that revenue is entirely footwear or zero haram revenue.
• Leather products: many footwear products use leather. Questions about slaughter, tanning, traceability, animal welfare and the treatment of finished consumer goods can differ; consolidated financial statements do not provide a screened leather numerator.
• Ownership: L Catterton is the ultimate controlling shareholder and is linked to LVMH. Ownership alone does not transfer every parent-company activity to Birkenstock, but governance, related-party transactions and capital-structure changes remain appropriate monitoring items.
• Debt and leases: the company reports EUR and USD term loans, a vendor loan and senior notes maturing in 2029. Lease liabilities and a tax receivable agreement are reported separately, so readers should avoid mixing those categories into a simplistic debt-to-market-cap claim.
• Ordinary operating risks: B2B and DTC mix, regional exposure, tariffs, inflation, distributor acquisitions and weather-driven seasonality affect the business and should not be presented as automatic Sharia verdicts.

How the methodologies differ

FTSE Yasaar's known asset ratios pass, but its income test is incomplete because gross interest income is unavailable. The MSCI total-assets and Malaysia SAC financial-ratio calculations pass their known financial tests. All three business screens remain incomplete because public reporting does not provide a reproducible product-level prohibited-revenue allocation. These are calculations against named methods, not official index-membership claims or a universal scholarly ruling.

Bottom line

BIRK is presented as generally permissible in core activity, with a methodology-dependent current screen. The known total-assets ratios are comfortable, while the main unresolved items are product-level skincare and accessory disclosure, leather and ingredient evidence, and the unavailable gross interest-income numerator.

If you are considering BIRK, compare this evidence with the methodology and scholar you follow, monitor the next filing and avoid relying on the old fixed debt-to-market-cap or purification claims that the current disclosure cannot reproduce.
